i want interval between column 2 and 1
column 3 and 2
column 4 and 3
column 5 and 4
column 6 and 5
and then i want
the result of those interval devided each other like:
interval column 3 and 2/ interval column 2 and 1
interval column 4 and 3/ interval column 3 and 2
interval column 5 and 4/ interval column 4 and 3
and soon

Azzi, I guess "so on". However, what does OP mean by "interval"?

Here's a wild guess at what you mean
diff(A(:,2:end),1,2)./diff(A(:,1:end-1),1,2)

A little more efficiently, then
temp=diff(A,1,2);
out=temp(:,2:end)./temp(:,1:end-1);
